Oil additives

[Paul Langley]

I was told if I used Mobil 1 synthetic oil I would have to use an additive.  But if I used Luiqi Moly oil no additive is necessary.  If an additive is necessary with Mobil 1, what is that additive?

 

thanks, Paul

Not sure who told you that you need an additive but Porsche does not recommend any additives.

I have owned Porsche's over 40 years and have never used (or needed) an additive.

Thanks Loren.  It was actually a shop that works on a fair amount of Porsche's.

Some shops make their money with "add on's" like this.  If you are using a quality full synthetic, you simply don't need additives.
